SOLEBURY TWP., Pa. (WPVI) -- As the search continues for four missing men in Bucks County, friends and neighbors are left with many questions.
On Tuesday night, friends of the missing four men - identified as 22-year-old Mark Sturgis of Pennsburg, 21-year-old Tom Meo of Plumstead, 19-year-old Dean Finocchiaro of Middletown Township and 19-year-old Jimi Tar Patrick of Newtown - kept vigil near the search site in Solebury Township.
"It's hard. We're all just shaken up by the whole thing. We're just scared. We just want to know something," friend Walter Marcinkowski said.
Crosby Cavanugh spoke about her friend Jimi Patrick.
"He was so close to me. That's one of my best friends. He was such a good person. Everyone deserves a Jimi in their life," Cavanugh said.
Marcinkowski says they were hanging out with Jimi Patrick on the 4th of July, the night before he disappeared. They went to school together at Holy Ghost Prep.
Until this investigation, Marcinkowski says he had never heard the name Cosmo DiNardo, a 20-year-old identified by Bucks County District Attorney Matthew Weintraub as a "person of interest" in the case.

"Never seen him before, never heard of the name," Marcinkowski said.
Brett Bergholtz, a friend of Dean Finicchiaro, says he too never heard of DiNardo.
"I just heard of it like now, I never heard of his name before that," Bergholtz said.

DiNardo was released on bail on an unrelated gun charge Tuesday; he has not been charged in connection with the missing men.
DiNardo's family owns the farm on Lower York Road in Solebury Township where the active search continued Tuesday.
The car of Tom Meo was discovered in a garage Sunday night at another property owned by the DiNardo family on Aquetong Road. But whatever the relation between DiNardo and the four missing men is something authorities are keeping close to the vest.
"We still have our investigators working on that; I am not at liberty to disclose that at this point," Weintraub said.
Neighbors and residents near the search area have been captivated since the investigation began.

"Everyone is just very concerned and worried. I think a lot of people are spooked," Sam Jarin of Plumstead said.
"I thought this doesn't happen in Solebury; this doesn't happen around here," Lisa Curreri of New Hope said.

"I feel for the families; it's so heart wrenching. I can't believe something like that is happening so close to here," Katie O'Connell of Solebury Township said.
Employees of local stores say customers and the community are asking questions.
"They've come in and asked what's going on around here. It's a tight-knit community and we're not really sure of anything," O'Connell said.
The sight of teams of law enforcement is now a constant for those near Route 202 in Solebury Township.
"Helicopters. All the time," resident Nancy Matusz.
In Bensalem, where Cosmo DiNardo lives on Wayland Circle, residents say they are seeing more marked units on patrol.
Resident Reggie Polk says police are telling neighbors to "be vigilant, keep your eyes open if you see anything suspicious with what's going on in the news."
Calls to the DiNardo family and Cosmo DiNardo's lawyer seeking comment were not returned.
